Behavioral addictions (BAs) are underrecognized, even in addiction programs. We assessed BAs in a substance abuse sample (n = 51; data collection 2011-2012). A self-report Behavioral Addictions Screen, assessing eight BAs, was administered using an automated telephone system. Most endorsed at least one BA, with the most common shopping/spending; eating; work; computer/internet; and sex/pornogra...

Considered a positive body image measure, the 13-item Body Appreciation Scale (BAS; Avalos, Tylka, & Wood-Barcalow, 2005) assesses individuals' acceptance of, favorable opinions toward, and respect for their bodies. While the BAS has accrued psychometric support, we improved it by rewording certain BAS items (to eliminate sex-specific versions and body dissatisfaction-based language) and develo...

Dysregulation in behavioral activation system (BAS) activity has been implicated in the pathogenesis of bipolar disorder (BPD). To characterize BAS activity and related facets in this disorder, the authors compared 59 participants with BPD to 44 controls on multiple measures of BAS activity, including a standardized behavioral task, self-reports, and electroencephalographic indexes of regional ...

Over the past two decades, the neurobiological substrates of the reinforcement theory have been discussed in terms of a behavioral activation system (BAS) and a behavioral inhibition system (BIS). While the BAS has been conceptualized as both an activating system and an approach-related system, the empirical evidence for either approach remains inconclusive. In the current study we hypothesize ...

Feeding bile acids (BAs) to rodents has been used to study BA signaling and toxicity in vivo. However, little is known about the effect of feeding BAs on the concentrations of BAs in serum and liver as well as the dose of the fed BAs that causes liver toxicity. The present study was designed to investigate the relative hepatotoxicity of individual BAs by feeding mice cholic acid (CA), chenodeox...

Bile acids (BAs) are important endogenous signaling molecules that play vital roles in the pathological development of various diseases including colitis-associated cancer (CAC). BAs were previously found dysregulated under conditions of CAC; however, the exact patterns and underlying molecular mechanisms remain largely elusive. Based on the development of a method for comprehensive analysis of...

Obeticholic acid (OCA) is a semisynthetic bile acid (BA) analog and potent farnesoid X receptor agonist approved to treat cholestasis. We evaluated the biodistribution and metabolism of OCA administered to carbon tetrachloride-induced cirrhotic rats. This was to ascertain if plasma and hepatic concentrations of OCA are potentially more harmful than those of endogenous BAs. After administration ...

Individual differences in sensitivities of the Behavioral Inhibition System (BIS) and Behavioral Approach System (BAS) have been posited to underlie stable differences in individuals’ unique patterns of responding to cues of punishment and reward in their environment. Conceived from the outset as neurological systems, the BIS and BAS have repeatedly been linked to brain structure and function t...

Apart from their pivotal role in dietary lipid absorption and cholesterol homeostasis, bile acids (BAs) are increasingly recognised as important signalling molecules in the regulation of systemic endocrine functions. As such BAs are natural ligands for several nuclear hormone receptors and G-protein-coupled receptors. Through activating various signalling pathways, BAs not only regulate their o...

Considered a measure of positive body image, the Body Appreciation Scale (BAS; Avalos et al., 2005) assesses acceptance of, favorable opinions toward, and respect for the body. Although the BAS was originally developed for and psychometrically examined with women, researchers are administering it to men and making gender comparisons. However, tests of measurement equivalence/invariance are need...
